闭环供应链运作中存在产品回收的逆向过程,从而由回收产品而生产的再制造产品与新产品之间存在质量差异,进而会引发不同的市场需求。基于此构建了由一个制造商和一个零售商组成的闭环供应链系统模型,并运用博弈理论分别在集中决策和分散决策两种情况下确定了最优产品定价策略与系统利润,并发现:供应链系统中通过集中决策来确定市场价格和回收价格的策略比分散决策要更低,系统利润也会相应的得到提高,为了使得系统中各个企业有实现集中决策确定定价策略的动力,给出了两种决策方式下差额利润的共享契约机制使得供应链系统达到协调。
There is a reverse process of product recovery in the operation of closed-loop supply chain, so there are quality differences between remanufactured products and new products produced by recycle products, which in turn will lead to different market demands. Based on this, a closed-loop supply chain system model consisting of a manufacturer and a retailer is constructed, and the game theory is used to determine the optimal product pricing strategy and system profit under the centralized decision-making and decentralized decision respectively. The results show that supply In the chain system, the strategy of determining the market price and the recovery price through centralized decision is lower than the decentralized decision, and the system profit will be correspondingly improved. In order to make all the enterprises in the system have the motivation to make a centralized decision to determine the pricing strategy, The two kinds of decision-making under the contract profit sharing mechanism makes the supply chain system to achieve coordination.
